Zo a/ZZ whom, t may concern.:

Be it known that we. @Hannes J. SHUTTLE- WORTH and OnvILLn M. Mouse, both of Springville, in the county of Erie and State of Kew York, have invented new and useful Improvements in Bolting Apparatus, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in io that class of bolting apparatus in which an inclined licking-surface is employed in connection with an elevating mechanism, whereby the material to be bolted is elevated from the bottom of the case and delivered near the upper end of the inclined bolting-surface, over which the material is caused to pass a great many times during the operation of bolting. A bolting apparatus of this character is described and shown in Letters Patent of the 2o United States No. 225,586, granted to usMarch 16, '1880, to which reference is here made for a full description thereof.

In the accompanying drawings, consisting of three sheets, Figure l is a side elevation of our improved machine. Fig. 2 is a top plan view thereof with a portion of the cover removed. Fig. 3 is a detached view showing the deflectiugboards in anoblique position.

Fig. et is an elevation of the tail end of the 3o machine. Fig. 5 is an elevation of the head end of the machine. Fig. G is a longitudinal section ofthe machine. Fig'. 7 is a cross-section in line a" m, Fig. 2. Fig. 8 is a longitudi nal section of the feed mechanism on an enlarged scale. Fig. 9 is an end view of the device whereby the screen of the feed mechanism is agitated. y

.Like letters of reference refer to like parts in the several figures. p

A represents the case of the machine, supported by a suitable frame-work, l?.

C is the elevating mechanism, of any suitable construction, that shown in the drawings consisting of a wheel or drum provided with longitudinal buckets c, applied to the periplr ery of the wheel.

D represents the inclined boltingsurface arranged on the descending side of the clevating mechanism, and consisting` of a suitable number of frames, d, covered with bolting- 5o cloth of various degrees of fineness. The frames d are held between parallel guides or ways E, ruiming lengthwise of the machine, and having an opening, c, through the tailboard of the machine for the introduction and 5 5 removal of the frames d.

D represents the inclined boltingsurface arranged on the ascending side of the elevat ing mechanism, and composed of frames d, covered with inciting-cloth, and secured re- 6o movably between parallel ways E, like the frames of the bolting-surface D. The boltingsurface which faces the ascending side of the elevating mechanism operates upon all the material which is spilled or dropped from the 6 5 elevating mechanism, thereby increasing the bolting capacity of the machine and shortening the length thereof. Y

F represents a knocker applied to the tail end of each'series of frames d, actuated by a 7o cam or erank,f, mounted on a horizontal shaft,

j", which is driven by bevel-gearsf2 from the rear end of the shaft of the elev-*ating'mechanism.

G is a screw-conveyer arranged underneath 475, each bolting-snrface, and provided with suitable slides, g g', which permit different parts of the bolted material to be drawn off separately, or to be remingled, as may be desired.

H represents the feedchamber, arranged up- 8o on the cover of the casing A of the machine, preferably over the ascending side of the elevating mechanism. It is provided in its bottoni with a number of openings, 71, li ha 7i lf, through either of which the material to be bolted may be introduced into the machine,and which are provided with slides e' fi' il ii, for opening and closing them.

J represents a screw-conveyor arranged on the bottom ofthe iced-chamber H, so as to con- 9o vey the material from t-he head toward the tail end thereof. The cour-'eyer-flights do not eX- tend quite to the head of the feed-chamber, so as to leave above the first feedopening, h, a space, j, in which the material is not moved horizontally by the conveyer. This space is preferably separated from the rest of the i`eed-V chamber by a concave partition, Lc, placed transversely upon thebottom of the feed-cham ber, between the rst and second openings, h h.'

L represents a spout `which conducts the material to be bolted to the space j' at the head of the feed-chamber.

M is an inclined screen arranged in the feedchamber above the head portion of the con; veyer J, so as to discharge the material which passes through the meshes of the screen into the conveyer-trough in rear of the partition 7c, While the tailings pass over the screen into the spacej in iront of the partition 7c. The screen M is pivoted or otherwise held at its upper end, and rests With its lower end upon the conveyer-shaft, which is provided at that point with cams or projections m, whereby the screen is jarred or agitated. The screen'M is made readily removable from the feed-cham ber through a slot, m', formed opposite the upper end of the screen, or in any other suitable manner.

N represents the spout which delivers the material to be bolted tothe head of the screen M. The latter is so clothed that it effects a separation of the coarser pa-rticles of bran from the rest ofthe Ground meal, the coarser parti-V cles passing over the tail of the screen into the chamber y', and the rest of the ground meal passing through the meshes of the screen into the trough ot the conveycr J.

O represents dei'lecting-boards arranged in the rear portion ot' the case A, opposite the upper descending side of the elevating mechanism. The boards O are arranged at suitable distances apart, and. secured with their outer sides to a strip ot' canvas, p, which is tacked to the inner side of the ease A; or they may be pivoted or hinged at their outer sides to the case of the machine in any other suitable manner. The boards O are connected at their inner ends, and simultaneously operated by a rod or bar, p, which projects through the tail-board ofthe case A, and is provided With a suitable handle at its outer end. Vhen the boards O are placed at right angles to the axis of the elevatingavhecl C, they do not affect the movement of the material through the apparatus; but when they are inclined toward the head of the machine, as shown in Fig. 3, the material discharged from the buckets of the reel is deflected toward the head of the machine, and its discharge from the machine is accordingly retarded. rlhe elevating mechanism is inclined toward the tail of the machine, like an ordinary bolting-reel, to give the material a tendency to work from the head toward the tail of the bolting-surface. Some*- times it becomes desirable to retain the material longer in the rear portion of the machine than it Would stay therein by reason of the inclination of the apparatus. This is readily accomplished by properly adjusting the deiiecting-boards O.

Q represents a spout, chute, or inclined conduit arranged against the under sideV of that portion of the bolting-surface through which pass the middlings of the rst separation. In small mills it is sometimes not possible to provide a separate bolting apparatus for the treatment of the reground middlings. When this is the case, We clothe the head of the bolting-surface with cloths, through which the iine flour and then the middlings of the reground middlings are bolted, and arrange the spout Q under that portion of the cloth through which the middlin gs of the reground middlings are bolted. The spout Q collects these middlngs and delivers the same into a separate receptacle, and the iiour from the reground middlings is collected by the head. portion of the conveyer G, an d discharged through the iirst slide, g. In this manner the products derived from the bolting of the reground middlings at the head of the bolting-snrface and the bolting of the ground Wheat through the remainder of the bolting surfacey are kept separate. The spout Q is so arranged in the machine that it can be readily applied or removed, as circumstances may require. The conveyers G G J are driven from a pulley, lt, mounted on the shaft of the elevating-Wheel C, by an endless belt, r, running over pulleys S on the conveycrshafts, or in any other suitable manner.

Then the machine is intended to be used for the bolting of ground Wheat or other material in a single operation, the spout Q is removed, and t-he Ways E are provided With frames d, having cloths of the requisite degrees of neness in the proper order, as may be n cc essary or suitable for the particular kind of Work which the bolt is intended to perform. The material to be bolted is introduced into the feed-chamber H through the spout L, and passes thence into the case of the machine through the iirst opening, h.

Vhen the material to be bolted is less in quantity than the capacity of the machine, it becomes desirable to shorten theV passage of the material through the machine in order to prevent the layer of the material which passes over the bolting-surface from becoming so thin that specks will pass through with the flour. This is accomplished by removing the bransieve M and introducing the material through the spout N, when the material is deliverd into the trough of the conveyer J, and may be admitted into the case A through either of the openings h h2 if h* at a greater orless distance from the head of the machine.

When it is desired to bolt both reground middlings and ground Wheat on the saine machine simultaneously, the bran-sieve M and the spout Q are replaced, and the bolting-sur :face is arranged for bolting reground middlings from the head to and including the sur- IOO IIO

face covered by the spout Q, and ground wheat from the spout Q to the tail of the machine. The ground wheat is introduced into the feed` chamber H through the spout N and the reground middlings through the spout L. The coarse bran is separated from the ground wheat by the sieve M, and passes over the tail thereof into the space j, and thence, together with the reground middlings, through the first opening, h, into the machine. All the finer portions of the ground wheat pass through the sieve M into the trough of the conveyer J, which conducts this material to the last opening, hi. The latter is located farther from the head of the machine than the spout Q, and admits the ground wheat into the machine at a point where the bolting of the reground iniddlings is completed, the intermediate slides being closed. By this means the coarse bran is made to traverse the entire boltingsurface, and is utilized first during the bolting of the reground middlin gs, which operation is greatly facilitated by the presence of the bran, and then comniingled with the ground wheat from which it was separated by the sieve M, and which it accompanies in its passage through the rest of the machine. Vhen the machine is so used, -the bolted middlings-flour is drawn off through the slide g, and the bolted wheatfiour, middlings, &c., through the slides g.
